Abstract
The utility model relates to power cable technical fields, especially a kind of power cable that fire resistance is strong, including cable core and sheath, the shield is set on the outside of cable core, on the inside of the sheath and outside is coated with fireprotection layer, and fireprotection layer includes the water-soluble resin dope layer being sprayed on sheath, chlorine polyethylene fireproof coating layer is also coated on the outside of the water-soluble resin dope layer, and it is also coated with silica sol layer on the outside of chlorine polyethylene fireproof coating layer, sealant is additionally provided with outside the fireprotection layer in outside.The utility model can be avoided since cable core either external temperature is excessively high, to cause cable bad, effectively increase the service life of cable.
Description
Technical field
The utility model relates to power cable technical field more particularly to a kind of power cables that fire resistance is strong.
Background technique
The use of power cable has over one hundred year history so far.1879, American inventor T.A. Edison was on copper rod
Wrapping jute is simultaneously penetrated in iron pipe, is subsequently filled asphalt mixture and cable is made.He in New York, starts this cable laying
Underground transmission.Next year, British Ka Lunde invention bituminizing paper insulation power cable.1889, British S.Z. took orchid
Ladder has laid 10 kilovolts of oil-impregnated paper insulation cables between London and moral spy Ford.1908, Britain built up 20 kv cable nets.
Power cable obtains increasingly wider application.1911, Germany's laying started the hair of high-tension cable at 60 kilovolts of high-tension cables
Exhibition.1913, German M. Huo Xishitaite was developed into individually screened cable, improves the distribution of cable internal electric field, eliminates
The positive shearing stress of insulating surface becomes the developing milestone of power cable.Nineteen fifty-two, Sweden lay in northern power plant
380 kilovolts of extra-high-tension cables, realize the application of extra-high-tension cable.The spy of 1100 kilovolts, 1200 kilovolts has been made to the eighties
High voltage power cable.With present cable use it is extensive, cable in the prior art there is fire protecting performance deficiency, when its week
The temperature enclosed is excessively high, will cause the damage of cable, for this purpose, we have proposed a kind of power cables that fire resistance is strong.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of fire resistance proposed is strong
Power cable.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of power cable that fire resistance is strong, including cable core and sheath are designed, the shield is set on the outside of cable core,
On the inside of the sheath and outside is coated with fireprotection layer, and fireprotection layer includes the water-soluble resin coating being sprayed on sheath
Layer, the water-soluble resin dope layer outside are also coated with chlorine polyethylene fireproof coating layer, and outside chlorine polyethylene fireproof coating layer
Side is also coated with silica sol layer, is additionally provided with sealant outside the fireprotection layer in outside.
Preferably, the sealant includes waterproof membrane and electrostatic prevention structure layer, and the waterproof membrane is arranged outside fireprotection layer
Side, the electrostatic prevention structure layer are sprayed on the outside of waterproof membrane.
Preferably, the waterproof membrane is specially polrvinyl chloride structure layer.
Preferably, the electrostatic prevention structure layer is specially polyethylene terephthalate's structure sheaf.
The utility model proposes a kind of strong power cable of fire resistance, beneficial effect is: the fire resistance is strong
Power cable, which passes through, is arranged in fireprotection layer inside and outside sheath, can be avoided since cable core either external temperature is excessively high, from
And cable bad is caused, the service life of cable is effectively increased, also by the setting of sealant, moisture is can be avoided and enters electricity
Inside cable, the electric conductivity of cable is impacted, guarantees the efficiency that cable uses.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of strong power cable of fire resistance structural schematic diagram.
Fig. 2 be the utility model proposes a kind of strong power cable of fire resistance fireprotection layer structural schematic diagram.
Fig. 3 be the utility model proposes a kind of strong power cable of fire resistance sealant structural schematic diagram.
In figure: 1 cable core, 2 sheaths, 3 fireprotection layers, 31 water-soluble resin dope layers, 32 chlorine polyethylene fireproof coating layers, 33 silicon
Sol layer, 4 sealants, 41 waterproof membranes, 42 electrostatic prevention structure layers.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of power cable that fire resistance is strong, including cable core 1 and sheath 2, sheath 2 are arranged in cable core
1 outside, 2 inside of sheath and outside are coated with fireprotection layer 3, and fireprotection layer 3 includes the water-soluble resin being sprayed on sheath 2
Dope layer 31,31 outside of water-soluble resin dope layer is also coated with chlorine polyethylene fireproof coating layer 32, and the fire prevention of chlorine polyethylene applies
32 outside of the bed of material is also coated with silica sol layer 33, in use, sheath 2 can play a protective role to cable core 1, and passes through setting
Fireprotection layer 3 inside and outside sheath 2 can be avoided since the either external temperature of cable core 1 is excessively high, so that cable be caused to damage
It is bad, effectively increase the service life of cable.
Sealant 4 is additionally provided with outside the fireprotection layer 3 in outside, sealant 4 includes waterproof membrane 41 and antistatic knot
Structure layer 42, for the setting of waterproof membrane 41 in 3 outside of fireprotection layer, electrostatic prevention structure layer 42 is sprayed on 41 outside of waterproof membrane, and waterproof membrane 41 has
Body is polrvinyl chloride structure layer, and electrostatic prevention structure layer 42 is specially polyethylene terephthalate's structure sheaf, in use, due to electricity
Cable is arranged in external environment for a long time, by the setting of sealant 4, can be avoided moisture and enters inside cable, to cable
Electric conductivity impacts, and electrostatic prevention structure layer 42, which can be avoided, occurs electrostatic around cable, ensure that the efficiency that cable uses.
More than, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, according to the utility model
Technical solution and its utility model design be subject to equivalent substitution or change, should all cover the protection scope of the utility model it
It is interior.
